1 Samuel 7:4

וַיְהִי מִיּוֹם שֶׁבֶת הָֽאָרוֹן בְּקִרְיַת יְעָרִים וַיִּרְבּוּ הַיָּמִים וַיִּֽהְיוּ עֶשְׂרִים שָׁנָה וַיִּנָּהוּ כָּל־בֵּית יִשְׂרָאֵל אַחֲרֵי יְהוָֽה

And it came to pass, from the day that the ark abode in Kiriath-jearim, that the time was long; for it was twenty years; and all the house of Israel yearned after the LORD.

וַיֹּאמֶר שְׁמוּאֵל אֶל־כָּל־בֵּית יִשְׂרָאֵל לֵאמֹר אִם־בְּכָל־לְבַבְכֶם אַתֶּם שָׁבִים אֶל־יְהוָה הָסִירוּ אֶת־אֱלֹהֵי הַנֵּכָר מִתּוֹכְכֶם וְהָעַשְׁתָּרוֹת וְהָכִינוּ לְבַבְכֶם אֶל־יְהוָה וְעִבְדֻהוּ לְבַדּוֹ וְיַצֵּל אֶתְכֶם מִיַּד פְּלִשְׁתִּֽים

And Samuel spoke unto all the house of Israel, saying: ‘If ye do return unto the LORD with all your heart, then put away the foreign gods and the Ashtaroth from among you, and direct your hearts unto the LORD, and serve Him only; and He will deliver you out of the hand of the Philistines.’

וַיֹּאמֶר שְׁמוּאֵל קִבְצוּ אֶת־כָּל־יִשְׂרָאֵל הַמִּצְפָּתָה וְאֶתְפַּלֵּל בַּעַדְכֶם אֶל־יְהוָֽה

And Samuel said: ‘Gather all Israel to Mizpah, and I will pray for you unto the LORD.’

וַיִּקָּבְצוּ הַמִּצְפָּתָה וַיִּֽשְׁאֲבוּ־מַיִם וַֽיִּשְׁפְּכוּ לִפְנֵי יְהוָה וַיָּצוּמוּ בַּיּוֹם הַהוּא וַיֹּאמְרוּ שָׁם חָטָאנוּ לַיהוָה וַיִּשְׁפֹּט שְׁמוּאֵל אֶת־בְּנֵי יִשְׂרָאֵל בַּמִּצְפָּֽה

And they gathered together to Mizpah, and drew water, and poured it out before the LORD, and fasted on that day, and said there: ‘We have sinned against the LORD.’ And Samuel judged the children of Israel in Mizpah.
